Thanks for checking out my work. All of my papers are available on my ResearchGate profile (I don't put them here because RG tracks all kinds of stats that I like).

Basic Visual Cognition

 
 
 

There's a lot of information out there in the world. Too much to process, in fact. Attention is the handy filter that picks out the good stuff so that you can ignore the noise. The factors that determine where and how attention is deployed form the cornerstone of more complex behaviours, such as action. However, we're still struggling to understand even the most basic principles of human attention. For example, if you want to understand how a human (or a self-driving car!) avoids obstacles, you first need to know how the visual system picks up suddenly transforming information on the road, or how attention separates objects from the environment. By understanding the principles of attention at a basic level, we can appreciate how we accomplish more difficult tasks.

Traditional approaches to the study of perception typically assume that perception is modular, which is to say that it's not affected by the way you think or act. Contrary to this notion, part of my research investigates the manner in which the ability to act modulates our perception of the environment. For example, underwater distances appear shorter when wearing flippers (effort-based scaling), and walls appear shorter when you can climb them (skill-based scaling).

One of the biggest problems our perceptual systems need to solve is how to isolate and represent the action-relevant information in the environment. For example, attention has built-in priorities for attending to things in the space near the hands, and the information that we attend to changes depending on what tools we're using.

Observing the actions of others implicitly activates a corresponding representation in the motor system of the observer, a phenomenon known as motor resonance. My research show that this sympathetic motor activation develops with practice in the perceived action. Interestingly, these simulations can occur simply by observing the 'trace' of an action. For example, piano players demonstrate this motor resonance when they hear a recording of piano performance, and most people demonstrate motor resonance when they observe a painting with evocative brushstrokes.
